The pattern in the number of glyphs, 7 + 6 + 7, we recognize:

At the beginning of side b in Tahua we have found the pattern 7 + 6 + 7 + 6 = 26. Experience from the centrally located 20-glyph sequence Hb7-7--26 gave the pattern 7 + 6 + 7 = 20.

My imagination tries to pursuade me that 7 + 6 + 7 means 'night', 'day', 'night' (or with other symbols with meaning the same: moon + sun + moon).

10 (months in a year) should be doubled into 20 because each month is divided in halves (waxing and waning). The year begins in darkness, then comes summer, then darkness returns. The day begins in the middle of the night, then sun arrives, then night returns.

7 + 6 + 7 = 20 is in symmetry with the play of light and darkness.

7 + 6 + 7 + 6 = 26 suggests the number of fortnights in a year.

7 is the number of days in a week and I realize how night (7) is in harmony with the hatch-marked henua at the beginning of each day in Hb9-17--58, e.g. in Sunday:

Let us examine the glyphs between Hb7-26 and Hb9-18 to see if the pattern with alternating 7 and 6 fills the whole interval.

Immediately beyond Hb7-26 we expect a sequence of 6 glyphs, then 7 glyphs etc. To begin with the prediction holds true:

Next group has 7 glyphs:

Then, as predicted, we have a group with 6 glyphs:

We could therefore stop here. The pattern beyond Hb7-26 was found to continue with alternating 7 and 6 for a period of 20 glyphs - yet another 20-group. After that a 20 group with a different numerical pattern broke the 7 followed by 6 pattern. 7 and 6 do not imprint all glyph sequences.

We will not stop here, however, because next follows something which realights our interest:

A glyph is (maybe) missing before Hb8-101. If so, then we have 6 glyphs again. Stimulated by this I reinvestigate the 20-group pattern which I considered was breaking down our numerical series of 7 and 6. I cannot let go of my idea about a pattern dark + light + dark:

This is an acceptable pattern with 7 + 6 + 7 I think. I have redmarked not only the 3 hanau glyphs, one in each subgroup (line in the table above), but also 4 'triple ball' glyphs, 1 in the beginning,1 at the end, and the remaining 2 marking beginning and end in the middle subgroup with 6 glyphs.

Obviously we should add 6 further glyphs to reach 26. The parallel glyph Pb8-37 signals reversal ('end') by having the 'Clara-knife' (if you remember) at left:

Now to the most interesting part: Metoro read neither of the texts H, P, Q but I feel confident that if he had done so he would have said pito (or something with a similar meaning) at Pa9-33 (probably also at Hb8-101).

Bb6-13 with a similar construction he read:

The pito at Hb8-101 (or to be more exact - including the missing glyph) arrives as number 21 in the 26 group, i.e. at the position of Hanga Hoonu in the corresponding 28 structure of Manuscript E:
